Archimedes was a Greek mathematician, inventor, and scientist who completed groundbreaking work in hydro-statics and geometry. He is also the inventor of the screw pump, known as the Archimedes screw.
Archimedes
Archimedes of Syracuse was a Greek mathematician, inventor and scientist. He was born in Syracuse, Sicily in 287 BC. He moved to Alexandria to study mathematics, but returned to Syracuse where he spend the rest of his life.
Archimedes produced a large amount of work in math, especially in geometry. Most famously, he wrote two volumes on the geometry of the sphere and the cylinder; he proved that the volume of a sphere was two thirds that of a cylinder. At his request there was a sculpture of a cylinder and a sphere on his tomb, as this was his favorite mathematical proof.
The king allegedly asked to investigate whether one of his crowns was pure gold or not. There were suspicions that the goldsmith had mixed the gold with other metals in an attempt to save money. Archimedes struggled to devise a way to measure the volume of the crown, which he needed to calculate the density. While taking a bath, he notice that the water rose when he got in. This made him realized that the increase in the volume of the water in the bath is equal to the volume of the object submerged. He could use this idea to measure the volume of the crown to calculate the crown’s density and compare this to the known density of gold. As well as this work he also produced other ideas in the field of hydrostatics. The Archimedes principle is important as it can describe buoyancy. The principle states that the upward force of buoyancy is equal to the weight of the liquid that is displaced by the object. This principle explains how ships and boats float on water.
He also produced a large amount of work in the field of mechanics. The earliest mathematical descriptions of a lever are from Archimedes. He famously stated “Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.” He is famous for the invention of the Archimedes screw, a simple machine that can be used to move water efficiently. In modern times, it has also been used as a method of generating electricity when connected to a generator. Archimedes also invented weapons, including a device which used mirrors to focus the Sun’s rays at enemy ships, setting fire to them. This idea has been tested in modern times, but has shown only to work in perfect weather conditions where there are no clouds in the sky.

How Tos about Archimedes Biography and Significance
How to Teach Archimedes’ Principle with a Simple Classroom Experiment
Engage students by introducing Archimedes’ Principle with a fun, hands-on activity that makes buoyancy easy to understand.
Gather materials for the experiment
Collect a clear container of water, a small plastic cup, modeling clay, and various objects (coins, erasers, marbles). Having supplies ready keeps lessons organized and reduces downtime.
Demonstrate floating and sinking
Ask students to predict if each object will float or sink, then drop them in water. Discuss observations to connect predictions with real results.
Create a model boat from clay
Challenge students to shape clay into a boat that can float and hold small weights. Show how design affects buoyancy and apply Archimedes’ Principle in a creative way.
Discuss real-world examples of buoyancy
Relate the experiment to everyday objects like ships or bath toys. Encourage students to think about where they see Archimedes’ Principle in action outside of the classroom.
Frequently Asked Questions about Archimedes Biography and Significance
Who was Archimedes and why is he important?
Archimedes was an ancient Greek mathematician, physicist, engineer, inventor, and astronomer. He is important for his major contributions to mathematics, especially geometry, and for inventions like the Archimedes' screw and his work on the principle of buoyancy.
What are some famous inventions by Archimedes?
Archimedes is especially known for inventing the Archimedes' screw (used for raising water), compound pulleys, and war machines such as the Claw of Archimedes and heat ray devices.
What is the Archimedes Principle?
The Archimedes Principle states that an object submerged in fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. This principle explains why objects float or sink in water.
How did Archimedes impact mathematics and science?
Archimedes made breakthroughs in geometry, calculated pi, and developed methods for finding areas and volumes of shapes. His discoveries laid foundations for modern physics and engineering.
Can you give examples of Archimedes’ work used today?
Applications of Archimedes' discoveries include water pumps (Archimedes' screw), ship design (buoyancy principle), and mathematical formulas for areas and volumes. His ideas are used in physics, engineering, and even everyday tools.
